Carboxymethylcellulose (CMC) yog tsim los ntawm fibers (fly / luv lint, pulp, thiab lwm yam), sodium hydroxide, thiab monochloroacetic acid. Raws li kev siv sib txawv, CMC muaj peb qhov tshwj xeeb: cov khoom lag luam ntshiab purity ≥ 97%, cov khoom lag luam purity 70-80%, cov khoom nyoos purity 50-60%. CMC muaj cov khoom zoo xws li thickening, suspending, bonding, stabilizing, emulsifying thiab dispersing hauv cov zaub mov. Nws yog cov khoom noj khoom haus tseem ceeb rau cov dej qab zib, cov khoom khov nab kuab, jams, jellies, kua txiv hmab txiv ntoo, flavorings, wines thiab ntau lub kaus poom. stabilizer.
Kev siv CMC hauv Kev Lag Luam Khoom Noj
1. CMC tuaj yeem ua rau jam, jelly, kua txiv hmab txiv ntoo, seasoning, mayonnaise thiab ntau cov kaus poom muaj thixotropy zoo, thiab tuaj yeem ua kom lawv cov viscosity. Ntxiv CMC rau cov nqaij hauv kaus poom tuaj yeem tiv thaiv cov roj thiab dej los ntawm stratifying thiab ua raws li huab cua. Nws kuj yog ib qho zoo tagnrho ua npuas ncauj stabilizer thiab clarifier rau npias. Tus nqi ntxiv yog kwv yees li 5%. Ntxiv CMC rau cov khoom noj pastry tuaj yeem tiv thaiv cov roj los ntawm cov khoom noj khoom haus, kom lub sij hawm ntev ntawm cov khoom noj pastry yuav tsis qhuav tawm, thiab ua rau lub pastry nto du thiab muag heev hauv saj.
2. Nyob rau hauv cov khoom khov nab kuab-CMC muaj zoo solubility nyob rau hauv ice cream dua li lwm yam thickeners xws li sodium alginate, uas muaj peev xwm kiag li stabilize mis nyuj protein. Vim tias cov dej tuav tau zoo ntawm CMC, nws tuaj yeem tswj tau qhov kev loj hlob ntawm cov dej khov nab kuab, kom cov dej khov nab kuab muaj cov qauv loj thiab lubricated, thiab tsis muaj cov dej khov seem thaum zom, thiab saj yog qhov tshwj xeeb zoo. Tus nqi ntxiv yog 0.1-0.3%.
3. CMC yog ib qho stabilizer rau cov mis nyuj haus-thaum cov kua txiv hmab txiv ntoo ntxiv rau cov mis nyuj los yog fermented mis nyuj, nws tuaj yeem ua rau cov mis nyuj muaj protein ntau condense rau hauv lub xeev tshem tawm thiab precipitate tawm ntawm cov mis nyuj, ua rau lub stability ntawm cov mis nyuj haus tsis zoo thiab nquag mus spoilage phem. Tshwj xeeb tshaj yog mus rau lub sij hawm ntev cia cov mis nyuj haus tsis tshua muaj neeg nyiam. Yog tias CMC ntxiv rau cov kua txiv hmab txiv ntoo los yog mis nyuj haus, qhov sib ntxiv yog 10-12% ntawm cov protein, nws tuaj yeem tswj tau qhov sib xws thiab ruaj khov, tiv thaiv cov kua mis protein los ntawm coagulating, thiab tsis muaj nag lossis daus, txhawm rau txhim kho cov kua mis zoo. , thiab tuaj yeem khaws cia rau lub sijhawm ntev. lwj.
4. Cov khoom noj hmoov - thaum cov roj, kua txiv hmab txiv ntoo, xim, thiab lwm yam yuav tsum tau ua hmoov, nws tuaj yeem tov nrog CMC, thiab nws tuaj yeem yooj yim hmoov los ntawm cov tshuaj tsuag kom qhuav los yog nqus cov concentration. Nws yog yooj yim soluble nyob rau hauv dej thaum siv, thiab cov nyiaj ntxiv yog 2-5%.
5. Hais txog kev txuag zaub mov, xws li cov khoom noj nqaij, txiv hmab txiv ntoo, zaub, thiab lwm yam, tom qab txau nrog CMC dilute aqueous tov, ib zaj duab xis nyias nyias tuaj yeem tsim rau saum npoo ntawm cov zaub mov, uas tuaj yeem khaws cov khoom noj rau lub sijhawm ntev. thiab khaws cov zaub mov tshiab, sib tw thiab saj tsis hloov. Thiab nws tuaj yeem ntxuav nrog dej thaum noj mov, uas yooj yim heev. Tsis tas li ntawd, vim tias cov zaub mov-qib CMC tsis muaj teeb meem rau tib neeg lub cev, nws tuaj yeem siv rau hauv cov tshuaj. Nws tuaj yeem siv rau CMC daim ntawv tshuaj, emulsified oil contaminating agent rau kev txhaj tshuaj, thickener rau tshuaj slurry, grave material rau tshuaj pleev, thiab lwm yam.
CMC tsis tsuas yog muaj ntau yam kev siv hauv kev lag luam zaub mov, nws tseem muaj txoj haujlwm tseem ceeb hauv kev lag luam teeb, textiles, papermaking, printing thiab dyeing, roj av thiab tshuaj txhua hnub.
